Cover for illuminant and lamp with cover

Abstract

A cover for a circuit board including LED illuminants and at least one connection terminals for connection cables on a top side of the circuit board, the cover including a receiving chamber for the circuit board; a light entry side oriented towards the receiving chamber; a light exit side arranged opposite to the light entry side; fasteners configured to arrange the cover at a light influencing component; optical elements arranged above the LED illuminants and configured to emit light emitted by the LED illuminants, wherein the cover forms a cutout for at least the one connection terminal between two of the optical elements that are adjacent to each other, and wherein the cutout is framed by the cover.

Description

RELATED APPLICATIONS[0001]This application claims priority from and incorporates by reference German Patent Application DE 10 2021 106 644.1 filed on Mar. 18, 2021.FIELD OF THE INVENTION[0002]The invention relates to a cover for a circuit board including LED illuminants and connection terminals for connection cables on a top side of the circuit board.BACKGROUND OF THE INVENTION[0003]Generic covers are known in the art in many shapes and are disclosed e.g; in DE 20 2019 106 117 U1 by applicant.[0004]A use of LEDs as illuminants in lamps typically requires covers in order to adapt radiation properties of the LEDs to a respective application through optical elements. Additionally, the covers are typically used to close the lamp in a light exit direction and in order to make it esthetically appealing.[0005]Increasing efficiency in lamp fabrication is paramount, in particular simplification of lamp assembly, wherein the new design options provided by a utilization of LED illuminants chan...

AI Technical Summary

Benefits of technology

[0008]Thus, it is an object of the invention to provide a cover which helps with simplifying and improving lamp assembly.

[0010]The cover described supra facilitates for the first time to attach the circuit board with the LED illuminants at the lamp component by applying the cover to the lamp component, in particular when the fasteners are configured as interlocking devices that reach behind the lamp component. Due to the recesses for the connection terminals in the cover wiring the circuit board can be performed after applying the cover and thus after fixing the circuit board since the connection terminals are accessible through the recesses of the cover. Providing the recesses with a circumferential frame makes the cover stable and fracture resistant.

[0014]The cable support formed by the cover provides a defined, orderly and positionally correct arrangement of the connection cables outside of areas that influence the light like e.g. the optical elements. This way a detrimental shadow cast by the cables is prevented. In particular it is possible due to the orderly and defined position of the connection cables that are received in the cable supports to keep the arrangement devices and arrangement surfaces for additional light influencing components like interlocking elements free from the cables which simplifies assembly of the light influencing components considerably.

Problems solved by technology

The technique proposed in DE 20 2019 106 117 U1 works well in principle but is not easily useable for covers that include additional lamp components on a light exit side, in particular screen elements configured to influence the light, which is typically caused by the constricted installation space and the restricted component visibility during lamp assembly.
